Alopecia Areata Types

Alopecia areata types

        The Alopecia areata is an autoimmune disease characterized by an unexplained loss of hair in some areas of the skin. It differs from baldness, which causes a loss of hair for reasons primarily hereditary. The Alopecia areata starts with one or two small areas, the size of a coin, completely bare. Its evolution is highly variable from one person to another. Typically, the skin of sufferers is dotted with areas. Approximately 1% of North Americans are affected by Alopecia areata.

• Androgenic alopecia (AAG): the male androgenic alopecia (AGH) and female (AGF). This is hair loss with age.
• Cicatricial alopecia: hair loss is the final result of a birth defect (congenital aplasia, Angioma), trauma (wounds, burns or surgery), a disease of the scalp (lupus erythematosus, lichen planus) or a tumor of the scalp (basal cell carcinoma, squamous cell carcinoma).
• Diffuse alopecia: overall decrease in density of hair.
• Localized alopecia: localized reduction of capillary density.
• Alopecia Areata total: complete baldness.
• Diffuse Alopecia Areata: An overall decrease of the hair. The diagnosis of diffuse Alopecia areata is difficult because it can be confused with other causes of diffuse hair loss.
• Alopecia Areata in small plates: most frequent alopecia areata.
• Severe Alopecia Areata: the alopecia areata covers over 50% of the entire scalp.
• Alopecia Areata ophiasique: This form of Alopecia areata affects the back and sides of the scalp (occipital and temporal regions). The treatment is more difficult and more frequently resistant to usual therapies.
• Subungual Alopecia Areata: Alopecia areata of the nails is manifested in general by abnormalities of the nail surface, it sometimes manifests itself in white or more rarely by loosened nails. Alopecia areata of the nails more often accompanies severe alopecia areata but can be isolated.
• Eyebrow Alopecia Areata: Alopecia areata of the eyebrows.
• Universal Alopecia Areata: The Universal Alopecia areata affects all areas of body hair (scalp, eyebrows and eyelashes, body hair, beard, armpits and genitals).
